Quantification of physical properties of fossil fuel fired flames is becoming increasingly important to achieve in-depth understanding and subsequent optimisation of combustion processes.

Fanatical love and hate their fires kindle flames of freedom".
On the remix of Birdman's "Fire Flame," he boasts, "They say it costs to be the boss/I paid the price, including tax".
Then, analyze its features such as fire flame color, spreading area, the similarity change, and fire smoke.
Before the fire flame reaches the ceiling, it increases very slowly with the fire size.
Dynamic characteristics are focused on by comparing two or more adjacent images in the video to judge the fire flame.
Thus, the fire flame could be eliminated and the propagation of explosion within the underground ventilation system is prevented.
Further, it can judge whether fire occurs from the characteristic information, such as the fire flame color, spreading area and the similarity change, and fire smoke.
